Twenty paired 14C and U/Th dates covering most of the past 50,000 yr have been obtained on a stalagmite from the Cango Caves in South Africa as well as some additional age-pairs on two stalagmites from Tasmania that partially fill a gap between 7 ka and 17 ka ago. After allowance is made for the initial apparent 14C ages, the age-pairs between 7 ka and 20 ka show satisfactory agreement with the coral data of Bard et al. (1990, 1993). The results for the Cango stalagmite between 25 ka and 50 ka show the 14C dates to be substantially younger than the U/Th dates except at 49 ka and 29 ka, where near correspondence occurs. The discrepancies may be explained by variations in 14C production caused by changes in the magnetic dipole field of the Earth. A tentative calibration curve for this period is offered.

AbstractEmphasis on the production of small unretouched blades is the strongest defining technological characteristic of southern African assemblages referred to as the Robberg – a ‘technologically uniform’ technocomplex identified across the sub-continent. This paper explores the spatial organisation of Robberg blade technology from three rockshelter sites in the Doring River catchment of the eastern Cederberg Mountains. The Doring is both a key source of water and toolstone, and the three sites are located at varying distances from it. Blades and blade cores from these sites are used to explore the influence of distance to source on the abundance of raw materials, staging of production and maintenance/reduction of transported artefacts. Results suggest key differences in procurement and provisioning strategies for different materials. Hunter-gatherers ‘geared up’ with hornfels and silcrete blades at the river before moving up the tributaries where toolkits were supplemented by small numbers of blades made from transported silcrete cores and the situational use of local rock types such as quartz. Results demonstrate the importance of understanding local-scale controls on technological organisation before inferring patterns of broader behavioural import.

Until now there have been no reliable historical or skeletal fossil records for the giraffe (Giraffa camelopardalis) south of the Orange River or northern Namaqualand. The recent discovery of fossil giraffe tracks in coastal aeolianites east of Still Bay, South Africa, significantly increases the geographical range for this species, and has implications for Late Pleistocene climate and vegetation in the southern Cape. Giraffe populations have specialised needs, and require a savanna ecosystem. Marine geophysical and geological evidence suggests that the broad, currently submerged floodplains of the Gouritz and Breede Rivers likely supported a productive savanna of Vachellia karroo during Pleistocene glacial conditions, which would have provided a suitable habitat for this species. We show evidence for the hypothesis that the opening of the submerged shelf during glacial periods acted as a pathway for mammals to migrate along the southern coastal plain.
